CF Series
A CF flange, which stands for "Conflat" flange, is a type of high-quality vacuum flange connection used in ultra-high vacuum (UHV) applications. CF flanges are specifically designed to provide a robust and reliable seal in vacuum systems. They are commonly used in scientific research, industrial processes, and manufacturing environments where maintaining a high level of vacuum is crucial.
Key features of CF flanges include:
1. Flat Sealing Surface: CF flanges have flat sealing surfaces, which ensures a uniform and reliable seal when mated with a compatible flange. This design minimizes the risk of leaks in high vacuum environments.
2. High-Quality Materials: CF flanges are typically made from high-quality materials such as stainless steel. This helps to maintain their integrity under vacuum conditions and prevents outgassing or contamination.
3. Bolted Connection: CF flanges are secured using bolts, creating a strong and secure connection. The number and size of the bolts can vary depending on the flange size and application.
4. Standardized Sizes: CF flanges come in various standard sizes, typically designated by a numerical value. For example, CF16, CF35, CF63, and CF100 are common sizes, each with specific dimensions and bolt hole patterns.
5. Cleanliness and Leak Tightness: CF flanges are known for their cleanliness and leak tightness, which is essential for maintaining a high vacuum and preventing contamination of the vacuum chamber.
CF flanges are widely used in vacuum systems for connecting various components like chambers, pumps, feedthroughs, and instrumentation. They have become a standard in the field of vacuum technology due to their reliability and effectiveness in maintaining ultra-high vacuum conditions.
